Xiaomi India — Service center is either fake or claims authorized

Address:

#6 ,Old, No 206, 7th Main Rd, Subbannaiah Palya, Bengaluru, Karnataka 560033

I had given my phone to the service center who claims they are tied up with the authorized service Mi centers. However i was given a 6 months warranty on my battery that was changed. I feel like the battery that was fixed is not original due to extreme phone heating and very poor battery back up.
